Given
Amount of contribution P = 500Interest rate r = 8% or 0.08Number of compounds n = 4Time t = 30 yearsFind the annuity using the formula below:
[tex]A= P*(1 - (1 + r/n)^{-nt})/(r/n)[/tex][tex]A= 500*(1 -(1+0.08/4)^{-30*4})/(0.08/4) = 22677.69[/tex]The volume of a rectangular prism box can be represented by the function V(x) = 2x3 + 5x2 − 3x. If the height of the box is x cm, which of the following can represent the length and width of the container?
The volume of a box is the amount of space in the box.
The expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]
The volume is given as:
[tex]\mathbf{V(x) =2x^3 + 5x^2 - 3x}[/tex]
Divide through by height (i.e x), to get the base area
[tex]\mathbf{A(x) =2x^2 + 5x - 3}[/tex]
Expand
[tex]\mathbf{A(x) =2x^2 + 6x - x - 3}[/tex]
Factorize
[tex]\mathbf{A(x) =2x(x + 3) - 1(x + 3)}[/tex]
Factor out x + 3
[tex]\mathbf{A(x) =(2x - 1) (x + 3)}[/tex]
Hence, the expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]

Help!!! Please answer all three of them
Answer:
Step-by-step explanation:
for the first one, solve by using the equation
180 = 43 + (x) + (x + 39)
137= x + x + 39
98 = 2x
x = 49
x + 39 = 88
for the second one, 5 and 7 are vertical angles, which are the two equal angles on opposite ends of an intersection. This means the answer is E.
for the third one, to find the exterior angle, you have to find that last angle inside the triangle. that means subtracting 85 and 65 from 180 to get 30. Now, subtract that 30 from 180 to get the exterior angle c. Straight lines are 180 degrees, so by finding that other angle and subtracting it from the total 180, you find the exterior angle. The exterior angle c is 150 degrees.
What is the total total amount of digits you need to number a book of 1150 pages
Step-by-step explanation: When numbering the pages of a book, which has 1,150 pages, we need: 9 one-digit numbers (from 1 – 9);90 two-digit numbers (from 10 – 99);900 three-digit numbers (from 100 – 999);151 four-digit numbers (from 1,000 – 1,150).
The total amount of digits you need to number a book of 1150 pages will be 3493 digits.
What is an arithmetic operation?It is described as the process through which we add, subtract, multiply, and divide numerical values. It has the fundamental operators +, -, and.
There are pages for the digits totaling,
Single digits : (1 - 9) = 9 pages
Double digits : (10 - 99) = 90 pages
Triple digits : (100 - 999) = 900 pages
Four digits : (1000 - 1150) = 151 pages
By summing all digit counts such as, one may determine the total number of digits.
= (9 + 180 + 2700 + 604)
= 3493 digits.
Thus, the total amount of digits you need to number a book of 1150 pages will be 3493 digits.

The difference of the square of a number and 12 is equal to 4 times that number. Find
the positive solution.
Answer:
12.3246
Step-by-step explanation:
The equation to be solved is [tex]x^{2} -10=4x[/tex]
Rearranging: [tex]x^{2} -4x-12=0[/tex]
The quadratic formula is one way to solve this equation.
[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a}=\frac{12+\sqrt{12^{2}-4*1*4} }{2*1}[/tex]
Note that only the positive variation of the quadratic formula was used. This is because it is the only variation of this formula that produces a positive result for this equation. This is not always true, so it is best to work both versions of the formula for problems like these.
[tex]x=\frac{12+\sqrt{160} }{2} =\frac{12+4\sqrt{10} }{2}=6+2\sqrt{10} =6+6.3246=12.3246[/tex]
If the negative version of the quadratic equation was used, the final (incorrect) answer would be x= -0.3246.

The Equation of line f is y =4/9x+3/2. line g is perpendicular to f. What is the slope of line g?
Answer:
slope of line g = -9/4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes:
m1 × m2 = -1 or [tex]m1 = -\frac{1}{m2}[/tex]
If the slope of line f = 4/9, as given the linear equation, y = 4/9x + 3/2, then the slope of line g must be -9/4. Because if you multiply both slopes, the product will be -1:
Let m1 = slope of line f = 4/9
m2 = slope of line g = -9/4
m1 × m2 = -1
[tex](\frac{4}{9}) (- \frac{9}{4})[/tex] = -1
Therefore, the slope line g = -9/4.

200 POINTS! PLEASE HELP!!!
You have $75 dollars to spend on side dishes for a party. Pasta salad costs $2.50 a pound and fruit salad costs $3.75 a pound. you must buy at least 5 pounds of pasta salad and 3 pounds of fruit salad. There are 40 people to feed and there needs to be at least a quarter of a pound of each side dish for every guest. You want to be able to buy the most amount of food for the party.
let x = pounds of pasta salad and y = pounds of fruit salad.
The objective function is f=x+y.
The vertices of the feasible region are (5,5) (5,16.6) (25.5,3) and (7,3)
what is the maximum amount of food you should buy?
how much pasta should you buy?
how much fruit salad should you buy?
Answer:
So, I cannot answer the whole question, but I can give you my thought process. SO, since you need to feed 40 people with a quarter of each meal - you would need 10 pounds of each dish. Therefore the information about the "least amount" of each dish is met. As mentioned, x = pounds of pasta salad, while y = pounds of fruit salad. this means x would equal 10 and y would equal 10. In order to find out what it would cost is:
2.50 x 10 = 25 ($25)
3.75 x 10 = 37.5 ($37.50)
the function could possibly be f=10+10?
The maximum amount of food you should buy would be 20 pounds of food, considering you need to have enough for each guest.
You should buy 10 pounds or $25 worth of pasta salad, and 10 pounds, or $37.50 worth of fruit salad.
